Part Datasheet Review

flux

The part currently only exposes the MPN and designator prefix; manufacturer, description, package, and datasheet URL are missing, so I’m searching for the official Harvatek source now.

flux

I found and set the Datasheet URL to the exact Harvatek v1.9 datasheet for the full MPN. I’m now checking the four-pin symbol and footprint against its polarity and recommended land pattern.

Done — I set the Datasheet URL to the exact Harvatek V1.9 datasheet and created the full review here: B38G3RGB-10D0003H2U1930 Part Review.
Open items:
  • Symbol pin descriptions are missing: Pin 1=G cathode, Pin 2=B cathode, Pin 3=common anode, Pin 4=R cathode.
  • Footprint pad numbering appears mismatched against the datasheet solder pattern.
  • Manufacturer/description/package metadata is still missing from visible part metadata.
Suggested next steps:
  1. Fix the symbol pin descriptions.
  2. Repair the footprint pad numbering to match the datasheet.
  3. Add missing metadata: Harvatek Corporation, LED, 0606/1616 metric, common-anode RGB SMD LED.

Datasheet pinout
Final pinout was resolved against the datasheet drawing and independent cross-check. One OCR/vector query produced a contradictory pin table, but the datasheet drawing/search corroboration supports the following:

1Green cathodeG cathode / G_K
2Blue cathodeB cathode / B_K
3Common anodeCommon anode / CA
4Red cathodeR cathode / R_K
Symbol cross-check
Current schematic symbol terminals are numeric-only terminals:

1Pin Number=1, Pin Type=Passive, no functional descriptionGreen cathodeMissing functional name/description
2Pin Number=2, Pin Type=Passive, no functional descriptionBlue cathodeMissing functional name/description
3Pin Number=3, Pin Type=Passive, no functional descriptionCommon anodeMissing functional name/description; common pin not identified
4Pin Number=4, Pin Type=Passive, no functional descriptionRed cathodeMissing functional name/description
Symbol finding: pin count matches, but pin descriptions/functions are absent. For an RGB common-anode LED this is a usability and wiring-risk issue because the common anode and RGB cathodes are not identifiable from the symbol metadata.
Footprint cross-check
Assuming conventional CAD coordinates with +X right and +Y up, the datasheet solder-pattern labels correspond to:

Equivalent coordinate map for the observed 0.45 mm x 0.8 mm pad centers:

Current embedded KiCad footprint asset map
The footprint asset content contains:

Table

(-0.45, +0.8)4
(+0.45, +0.8)3
(-0.45, -0.8)1
(+0.45, -0.8)2
Asset footprint finding: this is horizontally mirrored relative to the datasheet solder pattern under the conventional coordinate assumption. All four pad numbers are in the wrong physical positions vs the datasheet-required map.
Current PCB pad nodes observed
The PCB tree also reported pad nodes as:

Table

CoordinateCurrent PCB pad node
(-0.45, +0.8)1
(+0.45, +0.8)2
(-0.45, -0.8)4
(+0.45, -0.8)3
PCB-node finding: this mapping is also incorrect relative to the datasheet-required solder pattern; it resembles a 180-degree rotation of the required numbering. Because both an embedded footprint asset and PCB pad nodes are present and disagree, the active exported footprint should be repaired and re-export-verified rather than relying on either representation.
Coordinate/orientation caveat
Flux layout SVG rendering can invert Y for display, and LED datasheets can mix package top view and land-pattern view. The comparison above follows the explicitly labeled datasheet solder pattern and conventional +Y-up CAD coordinates. Even with display-orientation caveats, the current footprint data does not cleanly match the datasheet label relationships.
Mismatches / issues flagged
  1. Datasheet URL was missing — fixed by setting the exact V1.9 Harvatek datasheet URL.
  2. Manufacturer, description, part type, and package metadata are missing from visible part metadata.
  3. Symbol pin descriptions are missing for all four pins.
  4. Common anode is not identified in symbol metadata; pin 3 should be clearly marked common anode.
  5. RGB cathode functions are not identified in symbol metadata; pin 1 should be G cathode, pin 2 B cathode, pin 4 R cathode.
  6. Footprint pad numbering appears mismatched against the datasheet solder pattern.
  7. Embedded footprint asset and observed PCB pad nodes disagree with each other, suggesting the part footprint should be repaired and revalidated before use.
  1. Update part metadata: Manufacturer Name=Harvatek Corporation, Part Type=LED, Package or Case Code=0606 / 1616 metric, description=Top-view common-anode RGB SMD chip LED.
  2. Add pin descriptions/functions:
    • Pin 1: Green cathode
    • Pin 2: Blue cathode
    • Pin 3: Common anode
    • Pin 4: Red cathode
  3. Rebuild or edit the footprint so the active pad map follows the datasheet solder pattern:
    • Pin 3 at top-left
    • Pin 4 at top-right
    • Pin 2 at bottom-left
    • Pin 1 at bottom-right
  4. Re-run a layout/export check after footprint repair to confirm the exported land pattern matches the datasheet.
